What is 100GBASE-SR4
100G Ethernet is becoming more and more popular in the field of optical communication, and it has also formed a popular trend in the data center. What is 100G SR4? 100Gbase SR4 is an Ethernet standard that supports data rates of 100 Gbps. It uses four lanes to transmit data and uses a wavelength of 850 nm. 100Gbase SR4 is mainly used in short-range applications such as data center interconnects. Simply put, the transmission rate is 100G, and 100G is composed of four 25G channels. 100G QSFP28 SR4 has a 4-channel full-duplex transceiver module, each channel up to 27.952 Gbps data transmission rate, low power consumption less than 2.5W, QSFP hot-swappable package, 8/12-core MTP/MPO interface, through the use of multi-mode fiber, the maximum Transmission distance up to 100m, built-in digital diagnostic function (DDM).
100GBASE-SR4 optical module is mainly composed of five parts
The 100GBASE-SR4 optical module is mainly composed of five parts:
1- The first clock recovery module,
2- The array drive module,
3- The excitation and emission module,
4- The photoelectric conversion module and the electrical signal processing module,
5- Without using an optical multiplexer.
When the signal is transmitted at the transmitting end, the electrical signal is converted into an optical signal by 4 arrays of lasers, and then transmitted in parallel on the ribbon multi-mode fiber. When reaching the receiving end, the 4-array photodiode converts the parallel optical signal into a parallel optical signal. electric signal.
100GBASE-SR4 Application & Buying Guide
100G QSFP28 SR4 optical modules are mainly used in 100G data center switches, 100G high-end campus core switches, and 5G fronthaul networks, and play an intuitive and essential role in building 100G network systems. QSFP28 SR4 can be used in 100G Ethernet applications. It has a data rate of 100 Gbps and a reach of 70m over OM3 fiber or 100 meters over OM4 fiber. Such distance will enable the 100gbase sr4 to be used between rack mount servers connected by OM3/OM4 fiber cables in data centers. It uses 4 parallel 100G lanes in each direction over multimode fiber, with a data rate of 100Gbps full duplex. QSFP28 SR4 is mostly used for short-range applications. 100GBASE SR4 can be used in applications such as data center interconnects, high-performance computing, and cloud services. It provides high bandwidth and low latency. 100GBASE SR4 is also backward compatible with lower data rates such as 40Gbps, which gives you a smooth transition to higher speeds while protecting your investments in existing infrastructure and cabling.
All Transceivers are Widely Compatible
At present, QSFPTEK 100G QSFP28 SR4 optical modules are available at a very reasonable price, all transceivers are widely compatible with Cisco, Juniper, Brocade, Ubiquiti, and other OEM switches.
